Figure 6. EGCG and gemcitabine inhibit cell viability and STAT3 target genes.
(A), AsPC-1 and PANC-1 cells were treated with EGCG (0, 20, 40, 60 µM) with or without gemcitabine (0.5 µM) for 72 h. Cell viability was measured by XTT assay. Data represent mean ± SD. * or ** = significantly different from respective controls, P<0.05. (B), AsPC-1 and PANC-1 cells were treated with EGCG (0, 20, 40, 60 µM) with or without gemcitabine (0.5 µM) for 72 h. Apoptosis was measured by TUNEL assay. Data represent mean ± SD. * or ** = significantly different from respective controls, P<0.05. (C), Inhibition of STAT3 target genes by EGCG and gemcitabine. AsPC-1 and PANC-1 cells were treated with EGCG (20 µM) or gemcitabine (0.5 µM) for 48 h. The expression of VEGF, c-Myc, survivin and cyclin D1was was measured by qRT-PCR. Data represent mean ± SD. * = significantly different from respective controls, P<0.05.
